IMPROVEMENT IN COOKING-STOVE The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: air-draught between its upper edge and fire-plate A, Be it known that I, (JHAUNOEY O GREENE, f the in manner as shown, when it is arranged in the space city of Troy, in the county of Rensselaer, and State f made between the front plate and doors F and fire- New York, have invented a certain new and useful Im- Phlte and in whlhlhhtioh Wlth the 9 provement in Cooking-Stoves; and I do hereby declare apertures, y in the front Plate and Wlhh the 531d that the following is a full and exact description of the 'hd mid secured thereto by bolhs f by other same, reference being had to the annexed drawings, and Slllmhle means; so as to p y dmde the Space letters of reference marked thereon, making a part of between the front Plate and F and fire-Plate this specificati n i hi h; A, and separate therefrom, and thus form a permanent Figure 1 is perspective View f a cookinggstove distinct passage, a, between the said division-plateand embodying my improvem t 3, t f' th top d fire-plate A, and behindand separate from theiront front plates being removed, so as to show my inven- Plate and doors and next h P 1 tion more distinctl d formed between said division-plate B and front plate Figure 2 is a verti l ti f fig 1.

By thus dividing the space heretofore made between the front plate and doors and front fire-plate of oooking-stoves, into a distinct and permanent air-draught passage-way, next the fire-plate A, and an air-chamber, or space, next the front plate, or doors F D, when closed, a greater concentration or radiation of heat into the air-draught passage-way is obtained, to heat the In operating stove-furnaces, a hot-air draught supplied to the fire, is found to promote and perfect combustion of the fuel used therein, and devices for heating the air-draught for that purpose are now used.

The object of my invention is to improve and thereby provide a more effective device for heating a descending air-draught hotter, inits passage to the firebox, than hereto ore obtained, when occupying and passing down the entire space made between the front fire-plate of the fire-box and the front plate or doors of the stove; and I My invention consists in a division-plate, arranged in position between the front plate, or doors of the stove, and the front fire-plate of the fire-box, and in combination therewith, and the air-draught opening, or apertures, in the front plate, in manner so as to divide the space heretofore made between the front fire plate and front plate, or doors, and to form between the front fire-plate of the fire-box and the aforesaid division-plate, a permanent passage-way for a descending air-draught, that is distinct from the-front plate, or doors, and also form between said division-plate and front plate, or doors, an air-space, or chamber, in manand the p rp se herem set forth.

Having thus fully described my improvement in cooking-stoves,

What I claim as my invention, and desire to secure by Letters Patent, is-
